Description

Suture forceps under achilles tendon repair mirror

Technical Field

The utility model belongs to the technical field of medical machinery, and particularly relates to a pair of suture forceps used in an operation of repairing broken achilles tendon under an arthroscope.

Background

The endoscopic surgery is used as a minimally invasive surgery mode, and has the characteristics of less tissue stripping, small surgical wound and quick postoperative recovery, so that the application range is wider and wider, and the repair surgery for the rupture of the achilles tendon under the mirror is more and more emphasized in recent years. Different from open surgery, the operation space under the microscope is narrow (skin incision of 2 mm-5 mm), and the suture is difficult. The existing open suture surgical instruments are not suitable for being used under an endoscope, for example, a needle holder is used for clamping a surgical suture needle for suturing, but the existing usable endoscopic suture instruments are designed according to shoulder arthroscopic surgery, are generally large in size (shoulder joint lacunae is relatively large), are complex in operation steps and are not suitable for being used at the achilles tendon part. Therefore, under the condition of using the existing instrument, the repair technology under the Achilles tendon rupture mirror can be mastered only after the experience accumulation of the existing instrument for a long time, and a large amount of time is consumed for practice. Even experienced doctors, when performing suturing of the achilles tendon tissue under the mirror, it takes a long time, and the suturing accuracy and efficiency are not high.

SUMMERY OF THE UTILITY MODEL

Furthermore, the hinged end of the fixed clamp handle is connected with the fixed clamp rod, and the fixed clamp rod is of a hollow structure and is used for penetrating through the movable clamp rod, limiting the movable clamp rod and converting the rotation of the movable clamp rod into horizontal sliding. The fixed clamp rod is internally provided with a slide way which limits the movable clamp rod to slide on the slide way, so that the sliding of the movable clamp rod is smoother and more stable.

Furthermore, the fixed clamp mouth is arc-shaped and is bent towards the direction of the movable clamp mouth; the arc-shaped surface enlarges the space between the fixed forceps mouth and the movable forceps mouth, and is more beneficial to the joint between the forceps mouth and the achilles tendon tissue.

Furthermore, the fixed jaw is provided with a first hole for the movable jaw to pass through. The first hole can be in an oblong shape so as to be convenient for the movable clamp mouth to pass through. When the movable forceps mouth passes through the first hole, the suture line is driven to pass through the first hole, and one-time suturing is completed.

Furthermore, the hinged end of the movable clamp handle is rotationally connected with the movable clamp rod; the movable clamp lever can be driven to rotate by operating the movable clamp handle, so that the movable clamp lever can convert the rotation into horizontal sliding under the limitation of the fixed clamp lever.

Furthermore, the movable clamp rod penetrates through the fixed clamp rod, and the front end of the movable clamp rod is rotatably connected with the movable clamp mouth; the movable clamp rod can slide to drive the movable clamp mouth to rotate, and the movable clamp mouth can penetrate through the first hole of the fixed clamp mouth in the rotating process.

The movable clamp mouth is L-shaped and is bent towards the direction of a first hole of the fixed clamp mouth; when the movable forceps mouth penetrates through the fixed forceps mouth or the Achilles tendon tissue between the movable forceps mouth and the fixed forceps mouth, the needle point at the front end of the movable forceps mouth is over against the first hole of the fixed forceps mouth or the Achilles tendon tissue, and the movable forceps mouth is easier to puncture.

Furthermore, the front end of the movable clamp mouth is a needle point, and the rear part of the needle point is provided with a second hole for passing the suture. Wherein the second hole is oblong to facilitate passage of a suture therethrough.

When the fixed forceps mouth and the movable forceps mouth are in an occluded state, the size of the front end of the suturing forceps is smaller than 5mm, and the suturing forceps can smoothly pass through the endoscope working channel.

The utility model has simple structure and convenient operation, can be operated by one hand, and can assist surgeons in accurately and rapidly suturing the achilles tendon, shorten the operation time and reduce the operation and learning cost of the subascopic achilles tendon repair operation.

The utility model can pass through the joint puncture channel to operate in a narrow skin incision.
